Quantum search is a technique for searching $N$ possibilities for a desired target in $O(\sqrt{N})$ steps. It has been applied in the design of quantum algorithms for several structured problems. Many of these algorithms require significant amount of quantum hardware. In this paper we propose the criterion that an algorithm which requires $O(S)$ hardware should be considered significant if it produces a speedup of better than $O\left(\sqrt{S}\right)$ over a simple quantum search algorithm. This is because a speedup of $O\left(\sqrt{S}\right)$ can be trivially obtained by dividing the search space into $S$ separate parts and handing the problem to $S$ independent processors that do a quantum search (in this paper we drop all logarithmic factors when discussing time/space complexity). Known algorithms for collision and element distinctness exactly saturate the criterion.

In diesem Artikel führen wir mögliche Gründe an, dass Genossenschaften geeignet sind, komplexe Probleme in der Nachhaltigkeit zu lösen. Statt uns auf existierende Forschung zu stützen, ist der Inhalt dieses Aufsatzes hypothetisch und verbindet zwei Forschungsgebiete, nämlich Genossenschaften und komplexe Probleme. Komplexe Probleme wie der Klimawandel oder Ressourcenknappheit sind schwierig zu definieren und sind von verschiedenen Akteuren mit konkurrierenden Interessen und widersprüchlichen Anforderungen gekennzeichnet. In diesem Beitrag legen wir dar, warum und wie gewisse Eigenschaften von Genossenschaften sich für die Lösung von komplexen Problemen eignen - allen voran Nachhaltigkeit. Die Erörterung gliedert sich in zwei Teile: zuerst skizzieren wir die Charakteristika von komplexen Problemen und zeigen zwei Beispiele mit dem Schwerpunkt auf die Art der Problemlösungsfindung aus der Geschichte der Genossenschaften. In dem zweiten Teil des Beitrages beschreiben wir drei Merkmale von Genossenschaften, die aus unserer Sicht das Potential haben, zu Nachhaltigkeits-Herausforderungen beizutragen. Statt fertige Forschungsergebnisse zu liefern, möchten wir in der laufenden Diskussion aufzeigen, wie Genossenschaften zu den aktuellen Herausforderungen, mit denen sich die Gesellschaft konfrontiert sieht, beitragen können.

Decision making at every company is something very important and vital. Decision making can be influenced by several aspects, so it can affect the promptness and accuracy of the process, especially when solving any complex, dynamic and less structured problems. Therefore, the combination of multiple criteria concept and an application program of decision-support system is an effective way to generate alternative decisions. The methods used for multiple criteria are: Bayes method, MPE, CPI and the AHP. This article discusses the use of each method, adapted to each problem. The four methods happen to be very effective with the help of the application program of decision support system. Expectantly these methods are able to assist company managements in decision-making.

<span>Technology is increasingly being harnessed to improve the quality of learning in science subjects at university level. This article sets out, by incorporating notions drawn from constructivist and adult learning theory, a foundation for the design of an online environment for the acquisition of metacognitive problem solving skills. The capacity to solve problems is one of the generic skills now being promoted at tertiary level, yet for many learners problem-solving remains a difficulty. In addition, there are few instances of instructional design guidelines for developing learning environments to support the metacognitive skills for effective problem solving. In order to foster the processes of metacognitive skills explicitly in first year science students, we investigated areas where cognitive support was needed. The aim was to strengthen the metacognitive and reflective skills of students to assist them in adopting strategies and reflective processes that enabled them to define, plan and self monitor their thinking during problem solving. In tertiary science, both well-structured and ill-structured problems are encountered by students, thus a repertoire of skills must be fostered. A model for supporting metacognitive skills for problem solving is presented in the context of an online environment being developed at the University of New England.</span>
